The August 21, 2017 eclipse will be observable across America. While those in the path of totality will see a TOTAL solar eclipse, everyone will be treated to a PARTIAL eclipse. To help you celebrate this rare event, NASA released STL files for a 3D Printed Pinhole Projector in the shape of the USA and/or a US State.

You can also capture the moment: Ask a friend to take a picture of your shadow while holding your state’s pinhole projector. The resulting image will be a once in a lifetime picture of your shadow, the shadow of your selected state and a projected image of the partial eclipse marking your location!

And you can of course share the moment: by sharing your best images with us on Instagram, Facebook, Twitter and/or on NASA’s Solar Eclipse Flickr Group. Use #EclipseSelfie as a tag and leave a 1-2 sentence description of your image/idea.

3D Printed Pinhole Projection Cards

During the 2016 total solar eclipse in Micronesia, NASA engineers tested a variety of pinhole sizes using 3D printed cards . They found that a 5 mm pinhole held 3-4 feet above the ground provided the strongest and clearest pinhole projection of a partial eclipse.
